Yes, indeed. If you refresh often enough, you will notice the downvotes for a reasonable post come closest to when it is posted, which makes the post fade and gives the impression that something must be wrong with it. I think there is a very good chance this comes from people wanting to suppress information that does not support their position.

On an individual level the thing to do would be to upvote downvoted posts if they make some sense, they don't have to be great to be upvoted.
